Why water matters so much for guinea pigs
Like all living beings, guinea pigs require regular water intake as well. Water helps the organs function, maintains digestion, and helps to regulate the body temperature. Guinea pigs eat a high-fiber diet, consisting mostly of hay. Their digestive tract needs moisture to keep everything working properly.
Every guinea pig is unique. Some might drink a lot of water, while others drink a small amount each day. Some factors that influence this are diet, health, activity level, and environment. Regardless, the most important part is consistency and access. It is of utmost Importance that every guinea pig is given clean, fresh water every day.
The only daily liquid guinea pigs should drink Fresh Water
This is why plain water is all they should drink. Water is the only drink guinea pigs are allowed to have. Their bodies can process water, and anything added to it can be potentially harmful.
The most appropriate water
If your local water quality is safe, you can use tap water. If your area has very hard or has a lot of chlorine in your water, filtered water is a better option, but bottled water is also fine, as long as your tap water is suitable its generally unnecessary.
Steer clear of very long use of distilled water as this can cause their system to become unbalanced due to lack of minerals
Keeping their water clean
Your guinea pigs water should be refreshed daily. It may look clean, but without being visible, a clean water bottle or a bowl of water can easily become contaminated with dust from hay, saliva, fur, and bacteria. Use warm water and a bottle brush to clean your water bottles often.
Bottle or bowl of water?
Both of these options have their pros and cons. Water bottles are generally cleaner, but some guinea pigs find bowls more comfortable and they can be more natural. It is usually best to offer both to your guinea pig to ensure they are well hydrated.
Can guinea pigs drink anything else other than water?
This is where a lot of the confusion starts. Guinea pigs do have a very sensitive digestive system, and even a small amount of the wrong liquid can cause serious illness or discomfort. Water is the only drink they require every day, but there are a few rare exceptions, usually in some medical situations.
Never utilize these liquids for regular consumption.
Safe but Special Liquid for Guinea Pigs
Some liquids may be used temporarily under the supervision of an exotic-animal vet.
Unflavored Electrolytes
If dehydration occurs, a vet may advise for a short amount of time the use of plain unflavored Pedialyte, but this does not replace water. It is used temporarily to help restore hydration.
Critical Care
Critical Care is a powdered recovery food that is made specifically for small herbivores. When a guinea pig is unwell, loses weight, or is unable to eat, this powder is mixed with water to make a paste. It is nutritious and soft, and although water is used, the end product is food, not a drink.
Water with Medication
Sometimes a vet may ask you to put medication in water. That’s temporary and not meant to alter your guinea pig’s normal drinking pattern.
These milk exceptions are only for health purposes, and are not substitutes for water for otherwise healthy guinea pigs.
Liquids guinea pigs should never drink
The following section is arguably the most vital in this entire guide. There are countless liquids that, while seemingly benign or even beneficial to humans, can actually be toxic to guinea pigs.
Fruit Juice
Juices, even natural, contain sugars and acids that can be harmful to your pig’s digestive system and lead to diarrhea, obesity, and problems with teeth. Apple juice, orange juice, carrot juice, cranberry juice, and all other juices should be completely avoided.
Milk or Dairy of Any Kind
No form of dairy can be consumed as all milk from cows, goats, and all other animals cannot be digested. This leads to digestive problems that can be severe and/or painful.
Tea, Herbal Tea, or Coffee
Most herbal teas that are deemed as ‘mild’ or ‘calming’ are not safe. These contain certain herbs that are used as stimulants or are soothing in ways that are harmful as well as containing digestion interfering herbs. As for caffeinated beverages, they are especially harmful.
Flavored Water or Vitamin Water
Flavored waters or vitamin waters contain additives, sweeteners, and other unnecessary dyes that pigs cannot sustain. These also introduce an unsafe and irresponsible amount of certain nutrients.
Soda, Sports Drinks, or Energy Drinks
All of these contain carbonation, artificial flavors and sweeteners, colors, and caffeine. None of these belong anywhere near a guinea pig’s digestive system.
Coconut Water
Coconut water is not suitable for pig issues. Coconut water contains high sugars and high potassium as well which can disrupt a pig’s potassium and sugar levels.
Alcohol and Carbonated Drinks
These products are extremely risky and should not be offered to any animal, especially to sensitive ones like guinea pigs.

Signs Your Guinea Pig May Be Dehydrated
Identifying dehydration early on is necessary. Guinea pigs may have dehydration due to several reasons like illness, heat, stress, or dental problems.
Signs for dehydration include:
-
gums are dry or sticky
-
loss of energy or unusual tiredness
-
loss of appetite
-
urine is dark or more concentrated
-
fewer or smaller droppings
-
eyes are dull or sunken in
-
skin is not bouncy and stays loose when you pull it up
If your guinea pig shows these symptoms, see a vet as soon as possible.
How to Get a Guinea Pig to Drink More Water
Some guinea pigs tend to drink less than the average amount, and this is fine. You are just able to help them drink a little more and stay hydrated a little easier.
Ways to do this are:
Change Water Frequently
Even if the bottle isn’t fully empty, it’s a good habit to empty the bottle and give them fresh water daily. Guinea pigs seem to drink more if they feel they are getting fresh water.
Give Them a Water Bottle and Water Bowl
Some piggish like one over the other and this can help them not get dehydrated.
Hydrating Vegetables
Cucumbers, romaine, celery, herbs, and peppers are hydrating vegetables that can help keep animals well hydrated.
Check the Bottle for Issues
There are times that a water bottle gets stuck and water will not come out. It is a good idea to check your bottle to make sure the water is pouring out smoothly.
Keep Their Living Space Cool
High temperatures can make it harder for creatures to eat and drink. Helping keep a space well ventilated can help keep proper hydration.
Try Filtered Water
Like humans, some guinea pigs can be picky about water and may even prefer it to be filtered, especially if the tap water is quite mineral or chlorine rich.

Even from the plethora of drinks that exist in the human world, your guinea pig needs just one, that is, water. This drink, however, is in the very minimal aspect essential. It does a great deal, and is all that their very sensitive systems can handle. It plays a great role in digestion and other aspects of the body. It serves to be the main drink to regulate the temperature and is essential for the breathing of the body.
Sometimes, a vet might suggest an electrolyte drink or a specialized recovery mix, but such instances are infrequent, and very closely watched. They definitely cannot replace the pure, fresh water that every guinea pig needs every day. While giving a guinea pig some fancy drinks like flavored water, sweet juice, or herbal tea might seem like a nice gesture, the truth is those drinks are very bad for a guinea pig since their body is very sensitive and those drinks could cause a lot of problems.
